Abstract
Description
- The present invention relates to a system for the administration by infusion of substances such as, for example, drugs or food supplements, the system being as specified in the preamble of Claim 1.
- When administering active substances or solutions of active substances such as, for example, drugs or food supplements, which in the rest of this description will for simplicity's sake be termed active substances, by infusion, it is normal practice to use sterilized bags previously filled with injectable solutions for infusion into a patient. These bags have two openings on their lower edge into which two tubes are inserted; through the first of these tubes, the active substances are transferred from a storage container to the bag where they are mixed with the injectable solution. If the active substances contained in the storage container are, for instance, powders, some of the liquid contained in the bag is squeezed out of the bag into the container where it is used to dissolve the solid substances, after which the resulting solution is passed back into the bag, making use of the increased pressure created in the container.
- It is through the second tube that the resulting solution, which in the rest of this description will be described as the final solution, is administered to the patient.
- To perform the first stage, that is, transferring the active substances from the storage container into the bag containing the injectable solution, the tube intended for this operation is normally provided, at its free end, with a point having a plurality of holes, which point is positioned centrally inside connector means comprising a female component designed to fit exactly around the neck (the male component) of a container of active substances that are to be transferred into the bag containing the injectable solution. When performing this operation, the female component containing the point is pushed home over the neck of the container; the point simultaneously perforates an elastomeric plug normally used to seal containers of active substances and emerges on the inside of the latter. The system is then simply inverted and the active substance is transferred from the container to the bag, through the abovementioned point and tube.
- The German utility model DE-U-8812460 discloses a connector for an infusion system according to the preamble of claim 1.
- However, there is a problem with the system described above which cannot be ignored: since the connector component has to fit exactly around the neck of the container, it must be produced in many shapes and sizes, making it necessary to keep a different infusion system for each type of container. The significance of this problem will be understood when it is considered that a great many active substances are administered by infusion and that they are distributed in containers made in an enormous variety of shapes and sizes.
- Because these active substances are in daily use by hospital and clinical staff, these staff have to keep permanent supplies of the various transfer devices for the various containers of active substances. Nor should it be forgotten that very often these active substances have to be administered to patients in critical situations in which the person giving emergency aid cannot afford to waste time searching about for a bag with suitable transfer means.
- The problem with which the present invention deals is, therefore, how to provide a system for the administration of active substances by infusion that can be used independently of the size and shape of the neck of the container in which the active substance is stored and distributed by pharmaceutical companies, and which therefore solves the above problems.
- The problem is solved by a system for the administration of active substances by infusion as specified in the preamble of Claim 1 and having the features claimed in the characterizing part of Claim 1.
- The system according to the invention advantageously possesses the features claimed in the dependent claims that follow.
- Various preferred embodiments of the present invention will now be described, with reference to the accompanying figures in which:
- Figure 1 is a perspective view in partial section of a system for the administration of active substances by infusion.
- Figure 2 is a detail of the system depicted in Figure 1, showing how the active substance is transferred from the storage container to the bag for the final solution according to the present invention,
- Figure 3 shows a detail of another embodiment illustrating the connector plate and tubular perforator that fit onto the end of the tube through which the active substance is transferred, by screw means, and
- Figure 4 shows a detail illustrating an embodiment of the fastening and flow-prevention means according to the invention.
-
- With reference to Figures 1 and 2, the system for administering active substances by infusion, which has the general reference 1, comprises a
bag 2 having twoopenings 3 and 4 formed in its lower edge, aplate 5 of preferably circular shape containing acentral hole 6 in which there is force-fitted atubular perforator 7 having a point 8 at one end provided with a plurality of holes, of which there are two labelled 9 in this example, and barbed fastening means 23, the barbs being formed, in this example, by two pairs ofprojections 29 on opposite sides. In an alternative form, theplate 5 can be made in one piece with thetubular perforator 7, for example by injection moulding. - The point 8 of the
tubular perforator 7 projects from one side of theplate 5, while anend 15 of thetubular perforator 7 projects from the other. Thisend 15 is a connector component for atube 10 that allows fluid communication between thetubular perforator 7 and thebag 2. The point 8 of thetubular perforator 7 and the side of theplate 5 from which it projects are protected by acap 11, made of a soft plastic material and of a generally pointed shape with one end open. The open end of the cap is suitably shaped and contains anannular groove 12 which fits tightly around the edge of theplate 5. - One especially simple embodiment dispenses with the
plate 5 and, by way of an abutting member, exploits the fact that the diameter of theend 15 of thetubular perforator 7 is smaller than the external diameter of thetube 10, the former being inserted in the latter. The ring represented by the thickness of thetube 10 that surrounds theend 15 of thetubular perforator 7, thus assumes the function of the abutting member in place of theplate 5. - The
tube 10 comprises twoportions connector component 16 which includes flow prevention means 17. The flow prevention means, which include a breakable line that can be broken to allow fluid communication between thebag 2 and thetubular perforator 7, extend into the interior of theportion 14 of the tube and prevent any passage of fluid through theconnector 16, thus isolating thebag 2 from thetubular perforator 7. By this means the sterility of the injectable solution contained in thebag 2 during its storage is guaranteed. - As an alternative, the flow prevention means 17 are made in one piece with the
tubular perforator 7, as illustrated in Figure 4, in which case they once again include a breakable line and are essentially elongate. In this embodiment, theconnector 16 is no longer necessary and thetube 10 can be formed in one segment. - The
portion 14 of thetube 10 also possesses means 18 for pinching the tube: these consist of a clip which can be used to cut off the flow of active substance between thetubular perforator 7 and thebag 2 from the outside at any moment. - The
bag 2 is placed in fluid communication with the patient via the opening 4 and atube 19, to the free end of which a needle (not shown) is fitted for administering the final solution to the patient. Like thetube 10, thetube 19 is also divided into two portions connected by a connector component (not shown) identical in every respect to theconnector component 16 described earlier, in order to keep thebag 2 isolated from the external environment for the reasons cited earlier. - When the system according to the invention is to be used, the breakable line of the flow prevention means 17 is broken and, by keeping the system inverted to prevent the escape of the injectable solution from the bag, the fluid connection between the
tubular perforator 7 and thebag 2 is thus opened. At this point thecap 11 is detached from the edge of theplate 5 and thetubular perforator 7 is immediately used to perforate aperforable plug 20 of elastomeric material and of predetermined thickness, which seals acontainer 21 used to store the active substance prior to administration. Thetubular perforator 7 of the system is introduced into the fluid until theplate 5 is in abutment against theplug 20. The system is then inverted and, as also illustrated in the example of Figure 2, the active substance begins to flow through theholes 9 into thetubular perforator 7 and then through thetube 10 into thebag 2. The two pairs ofprojections 29 on opposite sides of the point 8 keep thetubular perforator 7 engaged inside thecontainer 21, so that thecontainer 21 cannot be accidentally disconnected from thebag 2. - On completion of the transfer, the
tube 10 is pinched off by the tube pinching means 18, leaving thecontainer 21 suspended from thetube 10. At this point, after briefly homogenising the active substance and the injectable solution in the bag, the final solution can be administered to the patient; to this end the flow prevention means blocking thetube 19 are broken and the solution is injected into the body of the patient. - An exemplary variant of the embodiment described immediately above is illustrated in Figure 3. Mounted on the end of the
tube 10, that is the end intended for connection to theplate 5, is afirst connector 24, preferably female. This connector is intended for connection to a correspondingsecond connector 25, which in the preferred case is male: thisconnector 25 is integral with thetubular perforator 7. The latter, exactly as in the first embodiment, possesses at one end a point 8 that projects from one surface of theplate 5, which point 8 and an opposing end (not shown), serve as a connector component designed to be connected with the corresponding end of thetube 10. - The
tubular perforator 7 is fitted with a cap (not shown) and also with adiaphragm 26 to seal off theend 15 of the male component of the screw coupling; thediaphragm 26 is of course removed immediately before theconnectors - As an alternative it is obviously possible to form the screw coupling by reversing the positions of the male and female components, so that the end of the
tube 10 has a male connector and thetubular perforator 7 has a female connector. - The invention is illustrated in Figure 4. The point 8 of the
tubular perforator 7 comprises a self-tappingthread 28 around an axial portion of itself designed to engage with the thickness of theplug 20 of thestorage container 21. Thetubular perforator 7 is therefore screwed through a half revolution into theplug 20 to secure it to thecontainer 21. - The system according to the present invention has the advantage of being usable with containers of all shapes and sizes and can therefore be bought in large quantities by hospitals or clinics for carrying out infusions of practically all the active substances available on the market.
- The presence of the abutment situated at a precise distance from the
holes 9 of thetubular perforator 7 also makes it possible to position them in the ideal position inside the container (close to the plug) and hence to transfer a quantity of the active substances from the storage container to the bag. - The embodiment which dispenses with the
plate 5 and uses the ring formed by the thickness of thetube 10 as the abutting member, has the particular advantage of being extremely simple and hence allows the manufacturing costs of the entire system to be considerably reduced. - The use of a screw coupling between the
tube 10 and thetubular perforator 7 has the additional advantage of supplying the two parts separately so that, should the point or other parts of the system be broken or contaminated as a result, for example, of inattention of the user during the various operations that precede the administration of the final solution to the patient, with this embodiment only one of the two parts need be replaced, rather than the whole system, thus reducing wastage of materials and money. - A person skilled in the art will be able to make many modifications and alterations to the system for the administration of solutions by infusion as described above, in order to satisfy additional particular needs, without however departing from the scope of the invention.
